Article Abstract
A set of 8 multiplex real-time SYBR Green PCR (SG-PCR) assays including 3 target primers and an internal amplification control (IAC) primer was simultaneously evaluated in 3 h or less with regard to detection of 24 target genes of 23 foodborne pathogens in 7 stool specimens of foodborne outbreak using a 96-well reaction plate. This assay, combined with DNA extraction (QIAamp DNA Stool Mini kit), offered detection of greater than 10(3)-10(4) foodborne pathogens per g in stool specimens. The products formed were identified using melting point temperature (Tm) curve analysis. This assay was evaluated for the detection of foodborne pathogens in 33 out of 35 cases of foodborne outbreak, using 4 different PCR instruments in 5 different laboratories. No interference from the multiplex real-time SG-PCR assay, including IAC, was observed in stool specimens in any analysis. We found multiplex real-time SG-PCR assay for simultaneous detection of 24 target genes of foodborne pathogens to be comprehensive, rapid, inexpensive, accurate, of high selectivity, and good for screening probability.

Rapid detection of live Salmonella typhimurium in food is critical for preventing contamination and protecting public health. Traditional methods, though reliable, are slow, costly, and require centralized labs. Many existing biosensors primarily detect dead bacteria, increasing false-positive risks.

Listeria monocytogenes is a saprophytic bacterium and a foodborne pathogen of humans and animals. Little is known about its distribution and genetic diversity across different environments within the same geographical region. We conducted a large-scale longitudinal study in southeastern Spain monitoring Listeria spp.

Foodborne diseases are caused by various pathogens and generally present with similar symptoms, mainly digestive disorders. Adopting a syndromic approach is therefore important when investigating foodborne disease outbreaks. This involves using multiplex PCR-based methods to test stool and food samples.

Cattle are a reservoir for the zoonotic human foodborne pathogen Shiga toxin-producing Escherichia coli (STEC), the causative agent of many disease outbreaks associated with contaminated fresh leafy greens. Concentrated animal feeding operations (CAFOs) housing cattle generate fugitive dust, however the potential risk of STEC movement by means of the aerosolized dust is not well known. In this investigation, we used metagenome sequencing of air samples collected in an agricultural setting to investigate airborne transfer of STEC from a large CAFO to the surrounding area.
